Analysis of 92 mitral pulmonary autograft replacement (Ross II) operations.

Objective: The study objective was to find a mitral valve substitute that does not require lifelong anticoagulation and is not affected by tissue degeneration in the long term.

Methods: Between July 14, 1997, and August 8, 2004, a total of 92 patients with irreparable mitral valve disease underwent mitral valve replacement with the pulmonary autograft encased within a Dacron tubing for support. In 4 patients, the autograft had to be sacrificed at the initial operation.
